I personally find locals() handy in few cases, like
def output():
foo = 42
bar = baaz()
quux = blah(foo, bar)
return "the %(bar)s is %(foo)d and the %(quux)s shines" % locals()
or:
class Foo(object):
@apply
def bar():
def fget(self):
return self._quux / 42
def fset(self, value):
self._quux = value * 42
return property(**locals())
I'd be very unhappy to see it gone...
